About SQK Jacketed Gate Valve

API 600 Gate Valves are distinguished by their robustness, durability, and quality with a reputation for reliability, integrity, and long service life.

The seals are designed for tight sealing and ease of use. Depending on the pressure rating, valves are available with flanged & butt-weld ends, and can be made from a variety of materials.

Wedges of this design feature an outside screw and yoke assembly and a bolted-bonnet. The valves comply with API 600.

Main features of SQK Jacketed Gate Valve:

The body-bonnet is bolted, the seals are welded, and the valves have pressure-sealing bonnets
Gate and globe valves with bellows-sealed seals are available
For maximum protection from leaks, body-bonnet joints are fitted with stainless steel gaskets and graphite fillers
Gate valves with T-head stem-disc connections fully meet API 602 and API 598 requirements
The stem features a rolled ACME thread for smooth operation
On the stem, the shoulder is tapered for back seating
The gland assembly has self-aligning studs and nuts for tightening
Seat for globe and check valves with integral hard-faced body
Electrical actuators are available for gate and globe valves
Inspiring optimal impact resistance, low heat loss and excellent corrosion resistance from austenitic SS forgings for cryogenic valve bodies and bonnets
We offer NACE MR-0175 valves and other NACE requirements as well

Optimal Thermal Regulation

Designed to maintain media temperature, the SQK Jacketed Gate Valve utilizes a carbon steel or stainless steel jacket. This facilitates efficient heating or cooling, making it ideal for processes that require thermal stability, such as in chemical and petrochemical plants.

Robust Construction and Wide Compatibility

Meeting ASME, DIN, and EN standards, this valve features a polished, straight body, full bore design, and bidirectional flow. Its flanged ends, bolted bonnet, and metal-to-metal sealing ensure tight connections and durability, suitable for demanding industrial settings.

Versatile Application Range

Handling temperatures up to 350C and pressure ratings spanning Class 150/300/600, this valve is suitable for oil, gas, steam, and chemical media. Available in multiple sizes, it is an essential component for industries requiring reliable and efficient process control.

FAQ's of SQK Jacketed Gate Valve:

Q: How does the jacketed design benefit temperature-sensitive processes?

A: The jacketed construction allows for external heating or cooling media to circulate around the gate valve body, effectively maintaining the temperature of process media and preventing solidification or viscosity increase.

Q: What media can the SQK Jacketed Gate Valve handle safely?

A: This valve is suitable for oil, gas, steam, and various chemicals, making it versatile for applications in the chemical, petrochemical, and process industries.

Q: When should I select a handwheel instead of a gear-operated valve?

A: Choose handwheel operation for smaller sizes (lower torque), while gear-operated types are preferable for larger valves or when frequent or precise control is needed.

Q: Where is this valve typically installed in a processing system?

A: It is commonly installed on pipelines carrying fluids that require temperature maintenance, such as near heat exchangers, reactors, or in lines handling viscous or solidifying materials.

Q: What is the process to ensure proper sealing after installation?

A: After installation, conduct a body test at 1.5 times the rated pressure and a seat test at 1.1 times the rated pressure, as per industry standards, to confirm leak-proof performance.

Q: How do I determine the appropriate port size for my application?

A: Select a port size (DN15 to DN300, 1/2" to 12") based on the pipeline diameter and flow requirements, ensuring compliance with ASME B16.10 face-to-face dimensions for compatibility.

Q: What are the main benefits of choosing the SQK Jacketed Gate Valve for industrial use?

A: Key benefits include excellent thermal regulation, robust sealing, compatibility with various standards, and suitability for a wide range of demanding temperature and pressure conditions.
